Do you have any good ideas regarding unified regulations for DCS configuration? Are there uniform requirements?
Thread Content
As the title suggests: In previous DCS configurations, I focused mainly on the functionality, integrity, and correctness of the system – such as seamless switching of the DCS system, ensuring that all instruments were properly configured without any omissions, implementing safety measures (like confirmation dialogs when the amplitude is too high), adding hyperlinks to various screens, aggregating monitoring displays for pumps and machinery, compiling displays for material measurement instruments, as well as creating communication interfaces for SIS instruments. I paid little attention to the aesthetic appeal of these screens, to their clarity and simplicity, or to the visual experience needed to prevent eye strain over extended periods of time； As a result, the configuration is carried out strictly in accordance with the PID drawings, which leads to a cluttered display after configuration: too many instruments are shown, and unimportant pipelines (such as those for sulfurization) are displayed on the DCS screen. Even circulation water cooling lines without any instruments appear on the screen and take up a lot of space. Problems: 1. How can the DCS configuration screen be made aesthetically pleasing and practical? What are everyone’s thoughts? 2. What are the unified regulations for DCS configuration? For example: Are there unified color specifications for common materials? Specifications for the background color (all black, gray, Raúl color, or RGB colors), specifications for the valve opening degree, configurations for control schemes, specifications for alarm levels, settings for hyperlink navigation, and so on. 3. How do people handle SIS configurations in a similar manner?
In accordance with the operational requirements, it is carried out by the operating technicians after they have a thorough understanding of the process flow.
As for the new device, it might be the first time that this new process is being configured – how can technicians gain a thorough understanding of it?
First, it is necessary to remove those pipelines that lack control points and display instruments and are not needed. It’s not the case that the more comprehensive everything is, the better; only the basic and complete process flow should be retained. Pipelines such as those for circulating water, fresh water, or startup/shutdown cycles should be removed, as DCS operations are carried out based on an understanding and familiarity with the site； Secondly is integrity; a single diagram can represent one process system, which may be an operational procedure or a device along with related processes. For example, in the case of atmospheric and vacuum distillation, this can include an electrical desalination system, an atmospheric distillation column system, and a vacuum distillation column system – all of these are organized around a key device. On the other hand, hydrogen-related facilities can be divided into reaction systems, distillation systems, utility systems, etc.
